asystem.com website review

Not measured in this review.

• Fails Core Web Vitals for real visitors

  Real Chrome users on phones do not pass Google's Core Web Vitals on your site (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

• Real-user CLS: 0.14

  0.14

  For real visitors the layout shifts by 0.14 (75th percentile). Good is under 0.1.

• Tap response (INP) held steady for real visitors

  -3%

  Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 205 ms to 198 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

• Page weight: 6.8 MB

  6.8 MB

  Your homepage downloads 6.8 MB on a phone, 2.8 MB of it images (41%). Under 2 MB keeps phones on slow connections fast.

• About 1.9 g of CO₂ per visit

  1.92 g

  By the Sustainable Web Design model, a visit to your homepage emits about 1.92 g of CO₂e: 230.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

• 1 text element with low contrast

  1 text element doesn't have enough contrast against the background to read easily, especially outdoors on a phone.

  Elements (1)

• 1 image without alt text

  1 image has no alt text, which hurts accessibility and image search.

• Landmarks should have a unique role or role/label/title (i.e. accessible name) combination (1 element)

  Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 1 element on the page fails this check, rated moderate by axe-core.

  Elements (1)

• All page content should be contained by landmarks (1 element)

  All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

  Elements (1)

• 42 links without text

  42 visible links have no text or label, so screen readers cannot say where they go.

  Elements (3)

• Headings skip levels

  Headings skip levels (h1 → h3), which makes the page harder to scan with a screen reader.

  View sourceElements (1)

• No structured data

  No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

• 3 H1 headlines

  There are 3 <h1> headlines (“Hero Banner”, “Our Scientific Advisory Board” and “Built to Higher Standards”). One clear main headline is easier for people and search engines.

  View source

• No X (Twitter) card tag

  No twitter:card tag. X falls back to Open Graph, which is set, so this is minor.

• 275 internal links, 4 external

  The homepage links to 275 pages on asystem.com and 4 external pages.

• No Organization structured data

  There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

• 3 pages without a meta description

  /pages/ingredients, /pages/third-party-tested and /pages/partnerships have no meta description, so Google writes the search snippet from whatever text it finds.

  Elements (3)

• 10 pages without an H1

  /collections, /collections/all, /collections/system-bundles, /collections/comprehensive-daily-nutrition, /collections/sleep and /collections/daily-focus-and-balance and 4 others have no <h1> headline, so visitors and search engines get no clear main topic.

• 15 internal pages checked

  We fetched 15 pages linked from your homepage (of 46 found) and read each the way a search engine does.

• 6 JavaScript errors while loading

  6 errors were logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

• Short HSTS lifetime

  HSTS is set, but max-age is 91 days; one year is the recommended minimum.

• No Referrer-Policy

  No Referrer-Policy header, so full URLs can leak to the sites you link to.

• No Permissions-Policy

  No Permissions-Policy header to switch off camera, microphone and location for embedded content.

• Deprecated X-XSS-Protection

  X-XSS-Protection is set to “1; mode=block”; the header is deprecated and can introduce bugs. Use 0 or remove it.

• No security.txt

  There is no /.well-known/security.txt telling researchers how to report a security problem to you.

• DNSSEC is off

  asystem.com's DNS answers are not signed. DNSSEC stops attackers forging them to send visitors or email elsewhere; most registrars switch it on in a click, though most sites still run without it.

• Local business without LocalBusiness data

  Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

• No phone number on the homepage

  A local customer looking to call finds no phone number on the homepage. Add one, ideally as a tap-to-call link.

• No direct contact details

  No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

• No opening hours

  The homepage shows no opening hours. If customers visit or call, show when.

• No map or directions link

  There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

• About 2,402 words of copy

  The homepage carries about 2,402 words of visible text.

• DMARC is monitor-only (p=none)

  DMARC is set to p=none, so mail pretending to be asystem.com is still delivered. Reports are on, so moving to quarantine is the next step.

• Email authentication score: 70/100

  Email authentication: SPF record 25 points, plus 15 when it ends in -all (10 for ~all); DMARC record 25, plus 25 for a reject policy (15 for quarantine); a DKIM key on a common selector 10.

• 8 trackers load before any consent

  8

  Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Klaviyo and Meta Pixel and 3 mores (measured from a US location before any click). No consent tool was detected. Visitors from the EU, UK and several US states must be asked first.

• 22 cookies set on arrival

  22

  Opening the homepage sets 22 cookies (measured from a US location before any click).

• No consent tool detected

  No known cookie consent tool loads with the page. Some sites build their own banner, and some only show one to visitors from the EU.

• 69 other companies contacted

  Loading the homepage contacts 69 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
